The Study of Chemical Interactions as Applied to Forensic Science.
Abstract
Adsorbent materials were prepared and found to show wide variation in their chromatographic performance. One of these showed excellent reversible adsorption of nitromethane, and even stronger possible adsorption of ethyleneglycoldinitrate. The use of such materials to preconcentrate explosive dopant vapors is quite promising. The adsorptive liquid chromatography of TNT was demonstrated using a PSDVB (poly(styrene-divinylbenzene)) adsorbent and ethanol as the moving phase. Polyvinylpyrrolidone was demonstrated for its use as a 'steric reagent' due to selective binding to HMX. A series of seven adsorbent polymers were tested for their value in RDX-HMX separations. The best selectivities were given (1) by the ammonium sulfonate form of PSDVB and (2) by polyvinylpyrrolidone.
